MISO maintains that a member request to create a multiday gas purchase requirement for use during extreme cold is unnecessary but offered financial assurances for resources whose commitments are canceled.

MISO’s Market Subcommittee likely will discuss either a multiday gas purchase requirement or a multiday gas unit commitment process for use during extreme cold.

MISO said it has landed on a final design in its quest to move to a sweeping capacity accreditation that will better measure generators’ availability based on predetermined risky hours.

An Iowa court has formally struck down the state’s right of first refusal law, driving uncertainty for $2.6 billion worth of MISO's long-range transmission projects.

MISO expounded on why its late August maximum generation emergency wasn’t met with prices dictated by its emergency offer floors.

MISO said it will push back a contentious filing for a new, marginal approach to capacity accreditation into early next year.

Doubts continue to swirl around which version of MISO’s future fleet mix is appropriate for long-range transmission planning — the Independent Market Monitor’s or the RTO’s itself.

Stakeholders remain frustrated with MISO’s plan to enact a marginal capacity accreditation as staff insist that the approach will measure the true value of capacity.

MISO will evaluate through the end of the year how it can measure and encourage six generating attributes that it says are necessary to its system operations.

An Iowa Utilities Board member said regulators are determining how the state Supreme Court’s temporary reversal of ROFR legislation will affect incumbent TOs.
